Groundwater Potential Zone Identification Using GIS: Mettur, Salem District, Tamil Nadu

Salem region is one of the drought inclined areas of Tamil Nadu. Being a rural zone, the area is finding a mitigation measure to keep the agribusiness on run. As a mitigation measure mapping the potential groundwater zones in the examination area will be a great alternate wellspring of water for the rural reason. The objective is to delineate the potential locations of groundwater zones using GIS software for the Metturtown panchayat, Salem district. The study area is inclined to drought. The different parameters that control the groundwater fluctuations, for example, geomorphology, contour, topography, LULC, soil; rainfall is broken down together as thematic maps. The slope map will be set up from DEM. These maps have been overlaid and the spatial analysis method, weighted overlay analysis using the GIS has been carried out. The ranking/weightage will be specified for every distinct bound of each thematic map. The weightages/rankings were relegated according to each thematic layer influence with respect to the Soil, LULC, and density of drainage, rainfall, and slope. The resultant maps display the groundwater potential zones ranging from very good to very poor zones
